Abstract
Third-generation advanced high-strength steel (TG-AHSS) recently garnered significant attention in the field of materials science and the automotive industry. This study focuses on the composition design, heat treatment processing, and mechanisms underlying the strengthening and deformation of TG-AHSS. The principle of composition design for TG-AHSS is expounded based on thermodynamic stability. Furthermore, several representative heat treatment processes are interpreted by generalized stability (GS). The strengthening and deformation mechanisms of the TG-AHSS are summarized from the perspective of the thermo-kinetic connectivity arising from the GS and the thermo-kinetic correlation. Finally, considering concurrently thermodynamics and kinetics, the design strategy of the TG-AHSS was summarized and outlooked.
